Cosmetics found use in both the genders especially among people of social standing and priests. A number of innovations in medicine and chemistry led to the advancement of the cosmetic industry. The beginning of 20th century marked the dawn of the cosmetic industry as newer innovations, advertising and faster communication led to introduction of cosmetics…show more content…
Nanotechnology involves manipulation of shape and size of materials / systems at the nano scale, the products having superior and unique properties compared to their larger form. Nanotechnology has been in use in the cosmetic industry since the last few decades with the introduction of niosomes by L'Oreal and liposomes by Christian Dior (Capture) in 1986 . Since then about 1300 products using nanotechnology have been introduced in the market targeting consumers with varied needs and expectations from cosmetic products. The global market for these products is expected to be worth 1 .36 trillion $ by…show more content…
Liposomes can be charged or zwitterionic whereas niosomes are neutral. Liposomes use more cholesterol resulting in reduced entrapment efficiency of actives . As compared to liposomes, they are more stable and also economical. Silicone vesicles (Patravale et al) have been successfully used as delivery system for actives especially for antiperspirants, fragrances and conditioning products. An example is aluminum zirconium tetrachlorohydrex GLY , an active commonly used in antiperspirants, when suspended in silicone vesicles results in lesser stickiness upon application and protect the active salts from degradation. The salts are released when the volatile silicone vaporizes. It was found that stearyl dimethicone also increased the SPF factor in sunscreens, in addition to improving fluidity and uniform spreadibility of the products on skin due to their high
